Bulk Username and Password Generation

In old Coursesites, the csv approach to bulk username generation was awkward but had some advantages over the email invitation system in Ultra. We run a very tight ship when it comes to child protection, and we had some control over username generation depending on how we recorded student names in the csv form, plus we had their passwords on file so we could troubleshoot their accounts if they were struggling with useability.

Neither are possible if we just invite them to self-enroll, which is essentially what inviting them via email is doing.
